There are other places in the world besides Wellington and San Francisco. The risk in Wellington is actually very high. It has its own version of the San Francisco earthquake in 1855, although a bit stronger. That earthquake uplifted quite a bit of land from the harbour which is now part of the CBD. That land is considered unstable, but has been built up with high-rise buildings. There's also a major fault line running right through the city, and the hilly landscape makes it vulnerable to landslides and road cut-offs. I'm surprised I got down-voted for mentioning it, but people are complacent I suppose.
